Member Function Documentation

◆ CheckStopBuffer()

Bool_t TGo4TaskHandlerRunnable::CheckStopBuffer	(	TBuffer *	buf,
		Int_t *	result = nullptr )

protected

Test if buffer contains a message to stop this runnable.

This mechanism is used to properly put taskhandler threads into parking position when connection is discarded. Value of buffer is set to external variable result optionally.
